    • setBuffered

      public Editor<T> setBuffered(boolean buffered)
      Description copied from interface: Editor
      Sets the Editor buffered mode. When the editor is in buffered mode, edits are only committed when the user clicks the save button. In unbuffered mode valid changes are automatically committed.
      Specified by:
      setBuffered in interface Editor<T>
      Parameters:
      buffered - true if editor should be buffered; false if not
      Returns:
      this editor

    • isBuffered

      public boolean isBuffered()
      Description copied from interface: Editor
      Returns whether Editor is buffered or not.
      Specified by:
      isBuffered in interface Editor<T>
      Returns:
      true if editor is buffered; false if not

    • isOpen

      public boolean isOpen()
      Description copied from interface: Editor
      Returns whether Editor is open or not.
      Specified by:
      isOpen in interface Editor<T>
      Returns:
      true if editor is open; false if not

    • save

      public boolean save()
      Description copied from interface: Editor
      In buffered mode calling save will validate bean and will save any changes made to the Editor fields to the edited bean if all validators pass.

      A successful write will fire an EditorSaveEvent and close the editor that will fire an EditorCloseEvent.

      If the write fails then there will be no events and the editor will stay open.

      Note! For an unbuffered editor calling save will have no effect and always return false.

      Specified by:
      save in interface Editor<T>
      Returns:
      true if save succeeded; false if not

    • cancel

      public void cancel()
      Description copied from interface: Editor
      Cancel will discard any changes made in editor fields for a buffered editor.

      Calling cancel will fire an EditorCancelEvent and close the editor that will fire an EditorCloseEvent if the edited item is not null.

      Specified by:
      cancel in interface Editor<T>

    • closeEditor

      public void closeEditor()
      Description copied from interface: Editor
      Closes the editor when in unbuffered mode and fires an EditorCloseEvent if the edited item is not null.

      For buffered mode calling close editor will throw an UnsupportedOperationException as either Editor.save() or Editor.cancel() should be used.

      Specified by:
      closeEditor in interface Editor<T>

    • editItem

      public void editItem(T item)
      Description copied from interface: Editor

      Specified by:
      editItem in interface Editor<T>
      Parameters:
      item - the edited item

    • refresh
